Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2012-3422)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The getFirstInTableInstance function in the IcedTea-Web plugin before 1.2.1 returns an uninitialized pointer when the instance_to_id_map hash is empty, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted web page, which causes an uninitialized memory location to be read.


2) Buffer overflow (CVE-ID: CVE-2012-3423)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The IcedTea-Web plugin before 1.2.1 does not properly handle NPVariant NPStrings without NUL terminators, which allows remote attackers to cause a denial of service (crash), obtain sensitive information from memory, or execute arbitrary code via a crafted Java applet.
